Moody’s has stripped the US of its top-notch triple-A credit rating as it warned about rising levels of government debt and a widening budget deficit in the world’s biggest economy.

Moody’s lowered the U.S. credit score to Aa1 from Aaa on Friday, joining Fitch Ratings and S&P Global Ratings in grading the world’s biggest economy below the top, triple-A position. The one-notch cut comes more than a year after Moody’s changed its outlook on the U.S. rating to negative. The credit assessor now has a stable outlook.
